水翼艇是一种专为高速减阻而开发的新船型。水翼攻角的改变会导致水翼艇阻力及航态发生变化。为探讨水翼攻角对阻力及航态的影响，获得阻力性能最优的水翼方案，本文以某全浸式双水翼艇为对象，基于CFD方法及重叠网格技术进行了不同艏翼攻角方案静水绕流场的数值模拟。研究表明，水翼有效降低了过渡状态及翼航状态下的船舶阻力，同时改善了船舶航态；过渡状态下首部水翼5°攻角时有最佳减阻效果；翼航状态下艏部水翼4°攻角方案有最佳减阻效果；攻角过大反而会增加船舶阻力并增大船舶尾倾。
Hydrofoil crafts are a new type of vessel developed with the aim of reducing resistance at high speeds. Variations of attack angle of the hydrofoils will lead to changes of hull resistance and gesture. In order to explore the influence of attack angles on hull resistance and gesture, and to obtain the optimal scheme with drag performance, this paper numerically simulates one fully-submerged hydrofoil craft equipped with T-shaped hydrofoils in still water based on the CFD method and overlapping grid technology, with the attack angle of bow foil as a variable. It is concluded that, in still water, the numerical results of resistance exhibit good grid convergence during the navigation. The presence of hydrofoils effectively reduces hull resistance and improves navigation state; the condition of optimal resistance reduction under the transition state occurs at an attack angle of 5°, while it occurs at an attack angle of 4° under the foilborne state; excessive attack angle will result to the increase of resistance and aggravate the pitch angle.
